little help with ADS7843

Ok Techu I will try as soon as I get home, one difference I did notice is I am creating the thread this way
chThdCreateFromHeap
And you are using this
chThdCreateStatic
This may be my problem..

[Tectu]

If you create a thread using chThdCreateFromHeap() you have to make sure that you have enough memory since it will be allocated dynamically. This routine should only be used when you create threads while run time. Threads, like yours, where you know that you will need it should be created using the chThdCreateStatic routine.

Ok Techu,
Your code worked fine, So I went back to my code and started to remove certain things and I have found the course of my problems..
sprintf
I use it twice in one thread and without them all of my code works fine including the buttons that toggle a led!
Is there a alternative to sprintf for drawing a ADC result??

[Abhishek]

Use chprintf, with a GWinConsole.

You can find a guide here: http://www.chibios-gfx.com/documentation/gwin/console .

What Abhishek said is totally accurate and might be the best solution for you.

Well I tried chprintf and it did the same thing, The working area of the thread calling it is sill 1024.
Are the print commands resource hungry?
I also tried to chprintf to console in Main thread and it also stops the code..

Please read this documentation explaining how to debug stack issues. I might have a look at your code tonight.
Just set the stack size higher and see yourself. Also check your optimization flags.
